Abstract

Cerium tungsten bronzes, Ce_x, WO₃ were prepared by the high temperature, solid state reaction of CeO₂, W, and WO₃. The intimately mixed reactants were sealed under a vacuum in quartz ampoules and heated for not less than 100 hours at 1050°C. The lattice parameter a₀ of the cubic bronzes was determined from Debye-Scherrer X-ray powder patterns. The cerium content of the bronzes x was established by isotopic dilution techniques. Cerium tungsten bronzes of cubic symmetry were found to crystallize in the range 0.070 < x < 0.186. The lattice parameter a₀ was found to increase linearly with x in the cubic range according to the relationship a₀ = 0.2165x + 3.8008.
